River stones are fully washed and scrubbed before construction, so that clean dust-free ash on the surfaces of the river stones is ensured.
For the cast-in-situ river stone landscape column of the river stone with the large grain diameter (300 mm-600 mm), the main keel and the secondary keel are installed after the whole column template is installed according to the dry barrier height of pebbles (rubble) and the reinforcement of Gao Luandan (rubble) with the height of 600mm each time.

And h-2, performing mortar pointing on gaps among the river stones 4.
The construction method of the cast-in-situ river stone landscape column is that a column core is arranged in the middle of a river stone (pebble or rubble) landscape column, the column core is a reinforced concrete structure (a reinforced skeleton and concrete), and a column core reinforced skeleton which is bound preferentially is used as a skeleton to which pebbles (rubble) are attached. The grid cloth wrapped outside the steel reinforcement framework can control concrete coarse aggregate not to run off between external pebbles (river stones), and meanwhile, concrete slurry can flow between pebbles (rubble stones) through the grid cloth to gap the pebbles (rubble stones). In addition, the mesh or the aperture of the mesh cloth wrapped outside the reinforcement cage is smaller than the grain diameter of river stones, and the pebbles (rubble) can be prevented from entering the reinforcement cage in the dry stacking process.
In the concrete pouring process, the embedded level occlusion between pebbles (rubble) can be more dense by adopting the vibrator for vibration. In the concrete pouring process, along with the concrete pouring into the flexible slurry leakage sleeve, under the vibration of the vibrating rod, coarse aggregate of the concrete presses the river stone outwards, and the positioning of the side template plays a limiting role on the river stone, so that the flatness of the river stone landscape cylindrical surface is ensured.
According to the cast-in-situ river stone landscape column, the column core is arranged in the middle of the landscape column, the column core is of a reinforced concrete structure, the column core reinforcement framework which is bound preferentially is used as a framework attached to a river stone dry barrier, the column barrel mould on the outer side can play a limiting role during concrete pouring, and the outer side of the column body is smooth through concrete pouring and vibrating. The cast-in-situ river stone landscape column has lower requirements on the appearance of river stone raw materials, and the construction of the river stone landscape column template with large grain diameter (300-600 mm) and small grain diameter (100-200 mm) is adjusted differently in the working procedure according to the material characteristics. And after the template is removed, deeply brushing concrete slurry on the surface of the river stone column to expose river stone.
The construction method of the cast-in-situ river stone landscape column completely changes the sequence of the traditional process (the sand masonry pebbles (rubble) and the cast-in-situ structural column externally attached pebbles (rubble)), and has high overall processing efficiency and good molding appearance quality. For the column with the river stone facing outside the structural column, the middle column core is designed according to the structural column and can be used as the structural column.
